Description

  The present invention relates to a method for controlling power supplied to an authentication device used in an entry / exit management system.

  As a countermeasure against the frequently occurring information leakage problem, an entrance / exit management system for managing the entrance and exit of people into offices and factories has been widely introduced. In the entrance / exit management system, a high level of security is maintained by authenticating a person entering or leaving the room using a predetermined method. For example, a non-contact type card is used as the most main authentication means because it can be easily used by a user and is excellent in durability without fear of wear or damage.

  A contactless card reader is used to read the contactless card. A contactless card reader needs to emit radio waves in order to detect a contactless card. However, there is a problem in that waste of power consumption increases if the wireless card is always in an activated state so that it can be detected whenever a contactless card is held over, and radio waves are continuously emitted.

  Patent Document 1 includes a contactless card reader / writer device and a control terminal capable of communicating with the contactless card reader / writer device, and a detection for detecting that a contactless card approaches the contactless card reader / writer device. There has been proposed a method in which a sensor is provided and a control terminal controls the power supply of the contactless card reader / writer device. In Patent Document 1, the control terminal turns on the power of the non-contact card reader / writer device when the detection sensor detects that the non-contact card approaches. When the contactless card reader / writer device reads an ID (Identification) number from the contactless card, the control terminal turns off the power of the contactless card reader / writer device. As a result, heat is not supplied to the non-contact card more than necessary, and heat generation of the IC chip of the non-contact card is suppressed, and even if the non-contact card is held over the non-contact card reader / writer device for a long time Chips and the like can be prevented from being destroyed.

  Further, by using the technique of Patent Document 1, the power consumed by the non-contact card reader / writer device itself can be reduced.

JP 2007-140966 A

  Since the above-described Patent Document 1 is mainly intended to prevent destruction of an IC chip or the like of a contactless card, the power source of the contactless card reader / writer device is controlled based on the proximity of the contactless card. However, the reduction of power consumption is not always achieved by the control for preventing such destruction, and the method disclosed in Patent Document 1 reduces the power consumption of the authentication device in the entrance / exit management system. In some cases, it was not an optimal control method.

  An object of the present invention is to provide a technique for optimally reducing power consumption in an entrance / exit management system.

When the transition to the normal state is made, the exit authentication apparatus is requested to shift from the normal state to the sleep state. When the transition from the state where no user exists to the management area to the state where the user exists, the transition from the sleep state to the normal state is performed. And a management server for requesting the leaving authentication device.

  In order to achieve the above object, the authentication device control method of the present invention is configured such that an authentication device for entrance installed at an entrance of a management area that manages entry / exit of a user has a user's access to the management area. The information required for authentication for entering the room is obtained, and the exit authentication device installed at the exit of the management area obtains information necessary for authentication for exiting the user from the management area, The management server acquires information necessary for the authentication from the authentication device for entering or leaving the authentication device, manages the occupancy state of the management area based on the information necessary for the authentication, and the management area Power supply to some devices except for the devices required for restart from the normal state where power is supplied to the authentication device for leaving the room from all the devices to the non-existing state. It is changed to the sleep mode to stop and shifts to the state where the user in the management area is present from the absence, shifts the exit authentication device from the sleep state to the normal state.

  In order to achieve the above object, the management server of the present invention is installed at the entrance of a management area that manages the entry / exit of the user, and is necessary for authentication for the user's entry into the management area. The entrance / exit device has an authentication device for entering the room and an authentication device for exiting that is installed at the exit of the management area and obtains information necessary for authentication for exiting the user from the management area.

(First embodiment)
In the entry / exit management system of the present invention, the management server that manages the user's occupancy status controls the power supply of the authentication device for evacuation according to the occupancy status. If no management room has entered the management area for managing the occupancy state, the management server causes the authentication apparatus for leaving the room to stop supplying power to some devices other than those required for restart. Then, when a new person enters the management area, the management server restarts the power supply to the device for which the power supply has been stopped.

  FIG. 1 is a block diagram showing the configuration of the entrance / exit management system of the first embodiment.

  As shown in FIG. 1, the entrance / exit management system includes a management server 1, an entrance card reader 2, an exit card reader 3, a door 6 and an electric lock 7.

  A door 6 is installed at the entrance of the management area where the entrance / exit management system manages the entrance / exit of the user. The door 6 is provided with an electric lock 7, and the opening and closing of the door 6 is restricted by the electric lock 7.

  The electric lock 7 is a lock for locking or unlocking the door 6. The electric lock 7 is connected to the entrance card reader 2 and the exit card reader 3, and the locking and unlocking of the electric lock 7 are controlled by the entrance card reader 2 and the exit card reader 3.

  The entrance card reader 2 and the exit card reader 3 are authentication devices that acquire information necessary for authentication for entering and leaving a user in a management area. The entry card reader 2 and the exit card reader 3 acquire information such as an ID assigned to the contactless card when the contactless card is held by the user. The entrance card reader 2 and the exit card reader 3 are connected to the management server 1 via a network, and transmit information acquired from the contactless card to the management server 1.

  The management server 1 is a computer that authenticates a user based on information received from the entry card reader 2 or the exit card reader 3.

  First, an outline of the operation of the entrance / exit management system of this embodiment will be described.

  When the user enters or leaves the management area, the user holds the contactless card over the entry card reader 2 or the exit card reader 3. The entrance card reader 2 or the exit card reader 3 acquires information assigned to the contactless card from the contactless card held by the user and transmits the information to the management server 1. The management server 1 authenticates the user based on the information acquired from the entry card reader 2 or the exit card reader 3, and transmits the authentication result to the card reader that is the transmission source of the information assigned to the contactless card. To do. The entry card reader 2 or the exit card reader 3 unlocks the electric lock 7 based on the authentication result acquired from the management server 1. As a result, the user can open and close the door 6.

  The configuration of the entry card reader 2 and the exit card reader 3 will be described below.

  The configurations of the entry card reader 2 and the exit card reader 3 are the same. Hereinafter, the configuration of the leaving card reader 3 will be described as a representative.

  FIG. 2 is a block diagram showing the configuration of the leaving card reader 3 according to the first embodiment.

  As shown in FIG. 2, the leaving card reader 3 includes a card control unit 21, an electric lock control unit 22, a network adapter 23, and a mode control unit 24.

  The card control unit 21 performs wireless communication with the contactless card held by the user, and acquires information such as an ID recorded on the contactless card. The card control unit 21 transmits an authentication request indicating an authentication request for entering / leaving the user holding the contactless card to the management server 1 via the network adapter 23. The authentication request includes information such as an ID recorded on the contactless card held by the user.

  The electric lock control unit 22 receives an authentication result for the authentication request from the management server 1 via the network adapter 23. The electric lock control unit 24 controls locking / unlocking of the electric lock 7 based on the received authentication result.

  The mode control unit 22 receives a start instruction or a stop instruction from the management server 1 via the network adapter 23. When the mode control unit 22 receives a stop instruction from the management server 1 while operating in the normal state, the mode control unit 22 stops the power supply to the room card reader 3 other than the network adapter 23 and the mode control unit 24, thereby reducing power consumption. It operates in the power mode (hereinafter, a state in which it operates in the low power consumption mode in which power supply to other than the network adapter 23 and the mode control unit 24 is stopped is referred to as a sleep state).

  Further, when the mode control unit 22 receives the activation instruction from the management server 1 while operating in the sleep state, the mode control unit 22 resumes power supply to the room card reader 3 other than the network adapter 23 and the mode control unit 24, The exit card reader 3 is operated in a normal state. When the exit card reader 3 enters a normal state, the card control unit 21 emits a radio wave for detecting the non-contact card, and waits until the user holds the non-contact card.

  In addition, as a command for starting instruction | indication and a stop instruction | indication, you may prescribe | regulate an interface uniquely between the server 1 and the card reader 2 for an entrance, and the card reader 3 for an exit, As a command for an instruction | indication of starting, A magic packet corresponding to WOL (Wake On Lan) may be used.

  The network adapter 23 performs control for communicating with the management server 1 via the network.

  The mode control unit 22 may be included in the network adapter 23. When a magic packet corresponding to WOL is used as a command for activation instruction notified from the management server 1 to the exit card reader 3, the network adapter and the PHY (Physical Layer) chip of the network adapter are the WOL. What has a function is used.

  Hereinafter, the configuration of the management server 1 will be described.

  FIG. 3 is a block diagram illustrating a configuration of the management server 1 according to the first embodiment.

  As illustrated in FIG. 3, the management server 1 includes an authentication unit 11, an activation instruction unit 12, and a network adapter 13.

  The authentication unit 11 receives an authentication request indicating an authentication request for entry / exit of the user from the entry card reader 2 or the exit card reader 3 with the contactless card held by the user. The authentication request includes information such as an ID recorded on the contactless card held by the user.

  Upon receiving the authentication request, the authentication unit 11 authenticates the information included in the authentication request, and transmits the authentication result to the card reader that transmitted the authentication request via the network adapter 13. The authentication unit 11 also transmits the authentication result to the activation instruction unit 12.

  When the activation instruction unit 12 receives the authentication result from the authentication unit 11, the activation instruction unit 12 determines whether the leaving card reader 3 is in a normal state or a sleep state according to the authentication result. The activation instruction unit 12 transmits an activation instruction or a stop instruction to the leaving card reader 3 through the network adapter 13 based on the determined result.

  The network adapter 13 performs control for communicating with the entry card reader 2 and the exit card reader 3 via the network.

  Next, processing when the management server 1 shown in FIG. 3 receives an authentication request from the entry card reader 2 or the exit card reader 3 will be described.

  FIG. 4 is a flowchart showing processing when the management server 1 shown in FIG. 3 receives an authentication request from the entry card reader 2 or the exit card reader 3.

  The authentication unit 11 of the management server 1 stands by until an authentication request is received from the entry card reader 2 or the exit card reader 3 (step S1).

  Upon receiving the authentication request, the authentication unit 11 authenticates the user who holds the contactless card over the card reader based on the information included in the received authentication request (step S2). The users who can enter and leave the management area managed by the entry card reader 2 and the exit card reader 3 are set in the management server 1 in advance.

  If authentication of the information included in the received authentication request fails, the authentication unit 11 notifies the card reader that transmitted the authentication request to that effect, proceeds to step S1, and waits until the authentication request is received again. To do.

  On the other hand, when authentication of the information included in the received authentication request is successful, the authentication unit 11 notifies the card reader that transmitted the authentication request to that effect, and further notifies the activation instruction unit 12 to that effect. To do.

  When the authentication result is received from the authentication unit 11, the activation instruction unit 12 determines the occupancy state of the management area before and after the authentication.

  First, the activation instructing unit 12 determines whether or not the authentication has shifted to a state in which no user exists in the management area (step S3).

  When the authentication makes a transition from a state in which no user exists in the management area to a state in which the user exists, the activation instruction unit 12 transmits an activation instruction to the leaving card reader 3 (step S4).

  On the other hand, if the authentication has not shifted from the state where no user exists in the management area to the existing state, the activation instruction unit 12 has shifted from the state where the user exists in the management area to the state where no user exists due to the authentication. Whether or not (step S5). When the authentication shifts from the state in which the user exists in the management area to the state in which the user does not exist, the activation instruction unit 12 transmits a stop instruction to the leaving card reader 3 (step S6).

  When the activation instructing unit 12 completes the determination process of the occupancy state of the management area that has authenticated entry / exit, the activation instructing unit 12 proceeds to step S <b> 1 and causes the authentication unit 11 to wait until an authentication request is received again.

  Next, processing when the user enters the room from the state where no user exists in the management area shown in FIG. 1 and then leaves the room will be described.

  FIG. 5 shows the relationship between the management server 1, the entrance card reader 2 and the exit card reader 3 when the user enters and exits from the state where no user exists in the management area shown in FIG. It is a figure which shows a sequence.

  First, there is no user in the management area, the entrance card reader 2 is in a normal state, and the exit card reader 3 is in a sleep state. At this time, when the user holds the contactless card over the entrance card reader 2 for entering the room, the entrance card reader 2 acquires information recorded on the held contactless card. Then, the entrance card reader 2 transmits an authentication request including the acquired information to the management server 1 (step S11).

  When the management server 1 receives the authentication request, the management server 1 collates the information included in the received authentication request with the information of users who can enter and leave the management area preset in the management server 1, and Authenticate users who hold a contactless card. When the information included in the received authentication request is successfully authenticated, the management server 1 notifies the entrance card reader 2 that the authentication has been successful (step S12).

  When receiving the notification that the authentication is successful from the management server 1, the card reader for room entry 2 unlocks the electric lock 7. As a result, the user can enter the management area.

  When the management server 1 notifies the entry card reader 2 that the authentication is successful, the management server 1 subsequently determines the presence state of the management area before and after the authentication (step S13). Since the authentication has shifted from the state in which no user exists in the management area to the state in which the user exists, the management server 1 transmits an activation instruction to the leaving card reader 3 (step S14).

  When receiving the activation instruction from the management server 1, the leaving card reader 3 supplies power to other than the network adapter 23 and the mode control unit 24, and shifts to a normal state (step S15).

  When the exit card reader 3 is in a normal state, it emits radio waves for detecting the non-contact card and waits until the non-contact card is held over. Thereafter, when the user who has entered the management area holds the contactless card over the exiting card reader 3 to exit, the exiting card reader 3 acquires information recorded on the held contactless card. Then, the leaving card reader 3 transmits an authentication request including the acquired information to the management server 1 (step S16).

  When the management server 1 receives the authentication request, the management server 1 collates the information included in the received authentication request with the information of users who can enter and leave the management area set in advance in the management server 1. Authenticate users who hold a contactless card. If the authentication of the information included in the received authentication request is successful, the management server 1 notifies the leaving card reader 3 that the authentication is successful (step S17).

  Upon receipt of successful authentication from the management server 1, the leaving card reader 3 unlocks the electric lock 7. As a result, the user can leave the management area.

  When the management server 1 notifies the leaving card reader 3 that the authentication is successful, the management server 1 subsequently determines the occupancy state of the management area before and after the authentication (step S18). Since the authentication has shifted from the state in which the user is present in the management area to the state in which the user is not present, the management server 1 transmits a stop instruction to the leaving card reader 3 (step S19).

  When receiving the stop instruction from the management server 1, the leaving card reader 3 stops the power supply to other than the network adapter 23 and the mode control unit 24, and shifts to the sleep state (step S20).

  As described above, according to the present embodiment, the card reader for leaving the room is controlled to operate only when there is a possibility of being authenticated by going into a sleep state when not in use and reducing power consumption. . Thereby, in an entrance / exit management system, power consumption can be reduced optimally.

  In this embodiment, an example is shown in which one entry card reader and one exit card reader are installed in one management area. However, the configuration of the entry / exit management system is limited to this. It is not a thing. For example, a plurality of doors may be installed for one management area, and an entrance card reader and an exit card reader may be installed in each door.

  At this time, if the user enters the room through one of the doors and shifts from a state in which no user exists in the management area to a state in which the user exists, the management server transmits an activation instruction to all the leaving card readers. The management server transmits a stop instruction to all the leaving card readers when the user leaves the door and shifts from the state where the user exists in the management area to the state where the user does not exist.

  As a result, even when a plurality of doors are installed for one management area, the power supplied to each leaving card reader can be controlled appropriately.

  Further, in the present embodiment, an example has been shown in which the management server authenticates the user for entering and leaving, but the present invention is not limited to this, and the entrance card reader or the exit card reader is used. May authenticate the user for entering and leaving the room.

  In this embodiment, an example in which a non-contact type card reader is used as the authentication device used in the entrance / exit management system has been described. However, the present invention is not limited to this, and the authentication device A magnetic card reader, a biometric authentication device, or the like may be used.

(Second Embodiment)
In the first embodiment, an example has been shown in which power consumption is reduced by controlling the operation mode of the leaving card reader in accordance with the occupancy status of the management area. By adding an infrared sensor for detecting a user to the configuration of the first embodiment, the power consumption can be reduced more efficiently. In the second embodiment, an example in which an infrared sensor is added to the configuration of the first embodiment will be described.

  FIG. 6 is a block diagram showing a configuration of an entrance / exit management system according to the second embodiment.

  As shown in FIG. 6, the entrance / exit management system of the second embodiment includes an entrance infrared sensor 4 and an exit infrared sensor 5 in addition to the configuration of the entrance / exit management system of the first embodiment. .

  The entrance infrared sensor 4 and the exit infrared sensor 5 are installed in the vicinity of the entrance card reader 2 and the exit card reader 3, respectively, and are connected to the management server 1. Examples of interfaces connected to the management server 1 include serial communication interfaces such as RS-232C (Recommended Standard 232 version C) and RS-485 (Recommended Standard 485).

  The entrance infrared sensor 4 and the exit infrared sensor 5 are installed in the vicinity of the entrance card reader 2 and the exit card reader 3, and monitor whether or not a user exists near each card reader. When detecting that there is a user within the monitored range, the entrance infrared sensor 4 and the exit infrared sensor 5 notify the management server 1 as detection information.

  FIG. 7 is a block diagram illustrating a configuration of the management server according to the second embodiment.

  As illustrated in FIG. 7, the management server according to the second embodiment includes an infrared sensor access unit 14 in addition to the configuration of the management server according to the first embodiment.

  The infrared sensor access unit 14 is connected to the room infrared sensor 4 and the room infrared sensor 5 and acquires detection information detected by each infrared sensor. Then, the infrared sensor access unit 14 notifies the activation instruction unit 12 of the acquired detection information.

  Based on the detection information received from the infrared sensor access unit 14, the activation instructing unit 12 determines whether or not to enter the room card reader 2 and the room exit card reader 3. The activation instructing unit 12 transmits an activation instruction to the entrance card reader 2 and the exit card reader 3 via the network adapter 13 based on the determined result.

  The configurations of the entrance card reader 2 and the exit card reader 3 are basically the same as the configurations of the entrance card reader 2 and the exit card reader 3 of the first embodiment.

  However, the mode control units of the entrance card reader 2 and the exit card reader 3 supply power to other than the network adapter and the mode control unit if a non-contact card is not detected in a normal state for a predetermined time or more. Stop and go to sleep.

  Next, processing when the management server 1 shown in FIG. 6 receives detection information from the room infrared sensor 4 or the room infrared sensor 5 will be described.

  FIG. 8 is a flowchart showing processing when the management server 1 shown in FIG. 6 receives detection information from the room infrared sensor 4 or the room infrared sensor 5.

  The activation instruction unit 12 of the management server 1 stands by until detection information is received from the room infrared sensor 4 or the room infrared sensor 5 (step S21).

  When the activation instructing unit 12 receives detection information from the room infrared sensor 4 or the room infrared sensor 5, first, the activation instruction unit 12 checks whether or not the card reader monitored by each infrared sensor is in a sleep state (step S22). .

  When the card reader monitored by each infrared sensor is in the normal state, it is not necessary to start again, so the start instruction unit 12 proceeds to step S21 and waits until detection information is received again.

  On the other hand, when the card reader monitored by each infrared sensor is in the sleep state, the activation instruction unit 12 transmits an activation instruction to the card reader (step S23). When the activation instruction unit 12 transmits the activation instruction, the activation instruction unit 12 proceeds to step S21 and waits until the detection information is received again.

  Next, processing when the room card reader 2 shown in FIG. 6 authenticates the user from the sleep state will be described.

  FIG. 9 is a diagram showing a sequence among the management server 1, the entry card reader 2, and the entry infrared sensor 4 when the entry card reader 2 shown in FIG. 6 authenticates the user from the sleep state. is there.

  First, the room card reader 2 has been in a sleep state for a predetermined period of time during which a non-contact card is not detected. At this time, when the user approaches the entrance card reader 2 to enter the management area, the entrance infrared sensor 4 detects that the user has approached the entrance card reader 2 and manages it as detection information. The server 1 is notified (step S31).

  When the management server 1 acquires the detection information from the room infrared sensor 4, it first determines whether or not the room card reader 2 is in a sleep state (step S32). Since the entry card reader 2 is currently in the sleep state, the management server 1 transmits an activation instruction to the entry card reader 2 (step S33).

  When the activation instruction is received from the management server 1, the entrance card reader 2 supplies power to other than the network adapter and the mode control unit, and shifts to a normal state (step S34).

  When entering the card reader 2 in a normal state, the card reader 2 emits radio waves for detecting the non-contact card and waits until the non-contact card is held over. Thereafter, when the user holds the contactless card over the entrance card reader 2 for entering the room, the entrance card reader 2 acquires the information recorded on the held contactless card. Then, the entrance card reader 2 transmits an authentication request including the acquired information to the management server 1 (step S35).

  When the management server 1 receives the authentication request, the management server 1 collates the information included in the received authentication request with the information of users who can enter and leave the management area preset in the management server 1, and Authenticate users who hold a contactless card. When the authentication of the information included in the received authentication request is successful, the management server 1 notifies the entrance card reader 2 that the authentication is successful (step S36).

  When entering the normal state, the entry card reader 2 monitors the time during which no contactless card is detected in order to determine whether or not the card reader 2 is being used. When the card reader 2 for entering the room determines that the non-contact card has not been detected for a predetermined time or more in the normal state (step S37), the entry card reader 2 transmits a stop notification indicating that the sleep state is entered to the management server 1 ( Step S38). Then, the card reader for room entry 2 stops the power supply to other than the network adapter and the mode control unit, and shifts to the sleep state (step S39).

  The processing of the leaving card reader 3 is basically the same as the processing of the entering card reader 2.

  First, the card reader 3 for leaving the room has been in a sleep state for a predetermined time or more during which no contactless card is detected. At this time, when the user approaches the leaving card reader 3 to leave the management area, the leaving infrared sensor 5 detects that the user has approached the leaving card reader 3 and manages it as detection information. The server 1 is notified.

  When the management server 1 acquires the detection information from the leaving infrared sensor 5, it first determines whether or not the leaving card reader 3 is in a sleep state. When the leaving card reader 3 is in the sleep state, the management server 1 further determines whether there is a user in the management area.

  When there is a user in the management area, the management server 1 transmits an activation instruction to the leaving card reader 3.

  On the other hand, if there is no user in the management area, the management server 1 determines that there is a trespasser in the room or that the infrared sensor has been detected erroneously, and issues an activation instruction to the card reader 3 for leaving the room. Do not send.

  Even if it is determined that there is no user in the management area, it is assumed that the user has accidentally entered the room due to a companion, etc., despite the failure of authentication. An activation instruction may be transmitted to the reader 3.

  When the activation instruction is received from the management server 1, the leaving card reader 3 supplies power to other than the network adapter and the mode control unit, and shifts to a normal state.

  Since the processing after the exit card reader 3 shifts to the normal state is the same as the processing of the entrance card reader 2, the description thereof is omitted.

  As described above, according to the present embodiment, the entrance infrared sensor is installed in the vicinity of the entrance card reader, and it is monitored whether there is a user in the vicinity of the entrance card reader. As a result, when there is no user near the card reader for entering the room, the card reader for entering the room is put in the sleep state, and when the user approaches, the card reader for entering the room can be set in the normal state, so that the power consumption of the card reader for entering the room is optimized. Can be reduced.

  In addition, according to the present embodiment, the leaving infrared sensor is installed in the vicinity of the leaving card reader, and it is monitored whether or not there is a user near the leaving card reader. Thus, even when there is a user in the management area, the exit card reader can be put into a sleep state when there is no user in the vicinity of the exit card reader. This can be further reduced than in the embodiment.

  In addition, when it is determined that there is no user in the management area when the person is detected by the leaving infrared sensor, the exit card reader is shifted to the normal state according to the operation of the entrance / exit management system. Alternatively, it may not be transferred. If it is determined that there is no user in the management area, the exit card reader can be prevented from operating erroneously due to erroneous detection of the exit infrared sensor by not moving the exit card reader to the normal state, and , Can prevent illegal intruders from leaving the room. Conversely, even if it is determined that there is no user in the management area, the card reader for leaving the room is moved to the normal state, so that the user may be mistakenly accompanied by authentication even though the authentication has failed. Even if the user has entered the room, a user-friendly operation can be performed so that the user can leave the room.
